Once the water is heated by the sun, how long will the water stay hot? Will the water still be warm/hot several hours after the sun goes down?

That depends entirely on what the air temperature is. Remember, this is just a plastic bag of warm water. The warmer the evening is, the longer the water will stay warm. You can touch the bag with your hand and determine if it's still warm.

Yes. We had it out all day and we got back 8pm and the water was still warm.

While I have never measured how long it takes to heat up, we leave ours in the sun all day and then use it in the evening--this works out fine for us. We use it on a sailboat and hang it from the bimini frame but if you are camping I suppose you could just hang it from a branch on a tree. There must be some type of surrounding structure you can hang it from!

It heats the water rather nicely. I have even had to turn the heat off because it got to hot. I still start with warm water just so it heats up faster but have put in cold water before. It took about 5 min to warm up to a nice temperature.

I presume that's what 'Keep Warm Heat' is. It probably won't warm up cold water, but if you put warm water in it, it should keep it warm for as long as you'd want to soak.

It stays hot for as long as any water that has been heated. It doesn't maintain a temperature.

The heater just keeps it so it won't freeze. It does not make the water hot. I think it stays about 32 degrees.

This unit does not actually HEAT the water. It only aids in maintaining the water temperature. Hot, or at least warm, water must be put into the unit. And even then it only does an adequate job of keeping the water warm. If the unit is turned off, the water will moderate or cool quickly.

There is no heating element to keep the coffee hot once brewed. It has a carafe that keeps the coffee hot. I have had a cup two hours after brewing and it is still hot. The water in the brewing process is heated to about 200 degrees. Highly recommend this product.

None...no real heat produced...you have to keep adding warm water to it....cools off right away

We have had ours for about 1 1/2 years. The housing gets a little warm, but, never hot. If we don't use the water for awhile, the water will be warm until it flushes out. Hope this helps.

If you thoroughly preheat the thermos with hot water it will stay hot for two days and warm for 3 days . This does depend on the temperature that is outside the thermos. If it is outside in very cold temperatures it will cool off faster .

Depending on how hot your water that you put in it is, anywhere from 20 to 30 minutes and it's still warm, then.Very nice product, we bought two of them. It's very malleable.

Lots of factors...what is water temp now? Where do you want it? How warm outside? Solar cover in place...couple degrees an hour is a rough estimate...good luck

Yes, it does. If you are nearby, you can hear it click off when it reaches the correct temperature. The water stays hot at least five minutes, in case you are busy with something else.

It will stay on and keep re heating the water,however,I wouldn't leave it on for hours,but if you were going to want to have a second cup in a half hour or so,you could leave it on as long as it has water in the little tank.

The beverage stays very hot for 2-3 hours. It will begin to cool down, but is still quite warm after the 3 hours. If you keep the lid in the closed position, it will stay very warm for a couple more hours.
